~~~~~ BEGIN ~~~~~
Gauge pressures
Low side 5 PSI, High side 90 PSI
Indicate low refrigerant level
Or blockage in system
Normal pressures are about
Blue, Low side, 35-45 PSI
Red, High side, 145-160 PSI

We will also be replacing the compressor
Low pressure cutoff sensor switch
Located on the Accumulator

In addition to gloves and safety glasses
I would recommend wearing a mask while blowing
Out the system so you aren't breathing
Atomized particulate solvent, oil, or any other debris
During the cleaning, flushing, purging process
Lay a towel over potential spray or burst situations

The picture in the manual was reverse for
The F250 5.4 liter Super Cab installation
Pay attention to how your orifice tube is inserted

The pipe immediately after the orifice tube should not be
Frosted and the two large return hoses and
The accumulator should be cold with condensation
On them.
This means a blockage at the orafice tube is causing
Not enough volume of coolant through the evaporator

You can see in the needle how the low side pressure switch
Activates the compressor when the low side pressure rises
Up to about 40 PSI
Then the low side pressure drops to about 35 PSI as the
Compressor begins to pump refrigerant again
At 35 PSI the switch senses a low pressure condition
This shuts off the compressor and low side pressure rises
Then low side pressure rises back up to 40 PSI
The compressor turns back on lowering low side pressure
Again starting the cycle all over
It creates a very narrow operational pressure window
